Abstract

<P>PROBLEM TO BE SOLVED: To provide a simple shaft seal for high pressure hardly to be influenced by run-out of the axis even in the case of using a high-pressure internal fluid. <P>SOLUTION: A rubber bushing 3 is pinched by an upper metal flange ring 2 on a plate 5 of a housing, and the surface thereof is formed with a slit 4 or a V-shaped ring by machining. A flange 1 being a rigid body rotated with a shaft 6 is rotated along the slit 4 or the V-shaped ring, and the fluid inside the housing is sealed by a repulsion force of the rubber bushing 3 between the bottom part of the slit 4 and the tip of the flange 1 being the rigid body. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

従来のシャフトシールのリップは、リップの素材が弾性体であり、又、リップが固定された状態で金属の回転シャフト表面と接触してハウジング内の流体をシールする構造の為、高速回転や軸芯のブレによってリップ自体が変形を余儀なくされ流体の漏れが発生され易く、又、エネルギー効率も低かった。The conventional lip of the shaft seal has a structure in which the material of the lip is an elastic body and the fluid in the housing is sealed by contacting the surface of the metal rotating shaft while the lip is fixed. The lip itself was forced to deform due to the blurring of the lead, and fluid leakage was likely to occur, and the energy efficiency was low.

当該技術The technology

当該技術は、回転軸の表面に剛体のフランジを固定させ垂直に立上がった鍔の先端部をリップとしてハウジングの開口部に固定されたスリップ又はV字型溝のゴム部の底辺を圧してその反発力でハウジング内の流体をシール構造の為、内部流体が高圧であっても軸芯のブレに対しても殆ど影響を受けることがない特徴のシャフトシールです。In this technique, a rigid flange is fixed to the surface of the rotating shaft, and the bottom of the rubber part of the slip or V-shaped groove fixed to the opening of the housing is fixed by using the tip of the vertically raised collar as a lip. The shaft seal features a structure that seals the fluid in the housing with repulsive force, so that even if the internal fluid is at a high pressure, it is hardly affected by shaft runout.

発明の詳細な説明Detailed Description of the Invention

当該発明は、装置のハウジング内の流体の回転軸(6)上からの漏れを防ぐ簡易高圧用シャフトシールで前記回転軸(6)上に剛体のフランジ(1)を固定し垂直に立上がった剛体リップ(1)の鍔の先端部をハウジング(5)の板の壁と剛体の上部フランジ(2)の内壁に囲まれたゴムブッシング(3)の表面に加工されたスリット又はV字型溝部(4)の底部を圧してその反発力で内部流体をシールする構造のシャフトシールで、前記ゴムブッシングの先端面のコーナーにアール(7)及び(8)が加工されているので剛体の上部フランジ環を押し込めば前記下部フランジ環の鍔の先端部を跨いで通り抜けて前記ゴムブッシング(3)表面に加工された前記スリット又はV字型溝(4)に嵌って自動的にロックされて装着され、前記回転体(6)と共転してハウジング(5)内の流体を密封する構造のシャフトシールです。  In the present invention, a rigid flange (1) is fixed on the rotary shaft (6) by a simple high-pressure shaft seal that prevents leakage of fluid in the device housing from the rotary shaft (6). A slit or V-shaped groove formed on the surface of the rubber bushing (3) surrounded by the wall of the plate of the housing (5) and the inner wall of the rigid upper flange (2) at the end of the flange of the rigid lip (1) (4) A shaft seal having a structure in which the bottom portion of the rubber bushing is pressed and the internal fluid is sealed by the repulsive force. Since the rounds (7) and (8) are processed at the corner of the front end surface of the rubber bushing, If the ring is pushed in, it passes over the end of the flange of the lower flange ring and fits into the slit or V-shaped groove (4) processed on the surface of the rubber bushing (3) and is automatically locked and mounted. The rotation (6) and rotation therewith and is shaft seal structure for sealing the fluid within the housing (5).
